Using AI for List Cleaning: All You Need to Know!

Any email marketer worth their salt has email hygiene pegged as one of their top priorities. And for good reason. It is, after all, the quality of your email list which has a bearing on the kind of engagement you are able to drive, and ultimately, the returns you pocket. 

Here are the key aspects of email list cleaning:

• Removing Invalid Addresses: This includes email addresses with syntax errors (e.g., missing “@” or “.”), non-existent domains, or email addresses that have been mistyped.

• Eliminating Disposable and Temporary Emails: Disposable email addresses are the ones with temporary or one-time-use email services. These emails should be removed from your list as they are unlikely to result in meaningful engagement.

• Identifying Role-Based Addresses: Email addresses associated with roles like “info@,” “support@,” or “admin@” are often monitored by multiple people and may not be appropriate targets for your campaigns.

• Dealing with Inactive Subscribers: Subscribers who haven’t engaged with your emails in a long time need to be removed or targeted with re-engagement campaigns to confirm their interest.

• Remove Duplicates: Duplicate email addresses in your list should be removed to avoid sending duplicate emails to the same recipient.

• Assessing Risk: Some email list cleaning tools use algorithms to assign risk scores to email addresses. High-risk addresses may include those associated with spam traps.

• Segmentation: After cleaning, you can segment your list into different categories based on factors like engagement history, location, or other relevant criteria.
• Regular Maintenance: Email list cleaning is not a one-time task; it should be performed regularly to keep your list accurate and up-to-date. Depending on your email volume, this could be done monthly, quarterly, or as needed.

• Compliance: Ensure that your email list cleaning practices align with relevant email marketing regulations, such as GDPR or CAN-SPAM.  Send emails to only those who have voluntarily signed up and have expressed their interest in receving your communications.

Why is email list cleaning important?

Email list cleaning offers several significant benefits for your email marketing campaigns and overall sender reputation. Here are some of the key advantages:

• Improved Deliverability: Cleaning your email list helps in removing invalid and outdated email addresses, reducing the likelihood of hard bounces. This improves your sender reputation and helps your emails reach the inbox rather than being flagged as spam.

• Higher Open Rates: A clean list contains engaged and active subscribers who are more likely to open and engage with your emails. This leads to higher open rates and potentially higher conversion rates.

• Reduced Bounce Rates:  A bounced email occurs because a receiver’s inbox is full, there’s an error in their address, or at times just a technical error. Either way, you want to keep your percentage of these down to keep your deliverability up. Removing invalid and non-existent email addresses reduces bounce rates, which is crucial for maintaining a positive sender reputation. 

• Cost Savings: . By removing inactive and unresponsive subscribers, you can reduce email marketing costs. The number of subscribers on your list is what determines the cost of the service you need to purchase. Naturally, more number of contacts translate to increased costs. So, you ought to exercise due diligence and weed out invalid contacts from your list; ensure all your marketing bucks are spent on people who are real and actively engaged with your emails.

• Lower Spam Complaints: Sending emails to unengaged or disinterested subscribers can result in spam complaints, which can harm your sender reputation. A clean list minimizes the risk of recipients marking your emails as spam.

• Compliance with Regulations: Cleaning your list ensures that you’re complying with email marketing regulations like GDPR and CAN-SPAM, which require you to obtain explicit consent from recipients.

• Better ROI: Ultimately, email list cleaning can fetch you a higher ROI for your email marketing efforts. You’ll be reaching a more receptive audience, which can translate into increased sales and conversions.
